Title: Method and apparatus for transferring data between disc and central processing unit
Inventor: YOUNG MARK S
IPC: G06F5/16
Filed: 1985-12-19
Abstract: A method and apparatus for transferring data between a disk and a CPU is disclosed comprising a pair of toggling header buffers and a pair of toggling data buffers. In operation, data is transferred between a sector on a disk and one of the data buffers under the control of one of the header buffers. While the data in the header buffer is being transferred between the data buffer and a CPU, data is transferred between an adjacent sector on the disk and the other data buffer under the control of the other header buffer. The rate of transfer of data between the data buffer and the CPU is higher than the rate of transfer of the data between the disk and the other data buffer. This provides sufficient time to check the data transferred from and to the CPU for errors and to address a new sector on the disk prior to the completion of the data transfer of the previous sector between the disk and the data buffer. By means of the method and apparatus disclosed, all sectors in a track on a disk can be transferred between a disk and a CPU within a single revolution of the disk.

IPC: H01F27/06
Filed: 1987-11-17
Abstract: PURPOSE:To fix content in a tank with high accuracy and to enable a transformer having desirable insulating properties to be constructed in small size, by applying laser light from the outside of the tank to a part where a clamp attached to the content of the transformer is in contact with the tank, and welding them thereby. CONSTITUTION:Content 22 consisting of an iron core and winding is inserted into a tank 21. A clamp 23 is attached to the top of the content 22 for fixing the content 22 in the tank 21. When the content 22 is inserted, a special-purpose guide not shown in the drawing is used for the purpose of ensuring positional accuracy in attachment of clamp 23. After insertion of the content 22, laser light 24 is applied from the outside of the tank 21 to the part where the clamp 23 is in contact with the tank 21 so that the clamp 23 is welded to the tank 21. Accuracy of the position of the applied laser light 24 is ensured by setting a reference point at a part of the special-purpose guide so that this reference point is the terminal point of the laser light. Further, the focal position of the laser light 24 is put on the plane where the inner surface of the tank 21 is in contact with the clamp 23, so that they are joined desirably at the joint section 25. In this manner, it is possible to prevent deterioration in insulating properties due to chips or the like during installment of the transformer.

CONSTITUTION:A first and second movable contact pieces 11, 12 are arranged in the same plane and parallel to each other, while a third movable contact piece 17 integrally molded with the lever 16 is arranged at a position opposing to the first and second movable contact pieces 11, 12 in a U-shaped bottom face part of the lever 16. Movable ends 11a, 12a of the first and second movable contact pieces 11, 12 are provided with insulating bodies 13, 14 respectively having plane parts in the same plane as contact point parts 11b, 12b. Even in a state where an oxide film and the like is produced on a surface of a contact point, the oxide film is destroyed by sliding movement of the third movable contact piece 17 provided in the lever 16 on the contact point parts 11b, 12b. A switch can be made inexpensive and excellent in contact reliability by only a silver plating process less expensive in cost in comparison with gold, its alloy or the like. Because of the arrangement of the first and second movable contact pieces 11, 12 in the same plane and parallel to each other, the insulating members can be integrated with the case so as to reduce component parts.

Title: Incinerator
Inventor: TANI NOBORU
IPC: F23G7/12
Filed: 1991-11-05
Abstract: PURPOSE:To avoid an explosion phenomenon caused by filling of non-ignited gas by a method wherein a fence composed of a plurality of vertical rods is arranged along an inner wall of a main body of an incinerator and passed through an accumulation region of ignited materials. CONSTITUTION:A fence 6 is comprised of a plurality of vertical rods 6a and vertically installed along an inner wall of a main body 1 of the incinerator and passes through an accumulation region of the ignited materials. A part of the fed ignited materials is prevented by the fence from its passing and another part of the material passes through the fence 6 and further advances to a wall 1a of the incinerator. The ignited materials are accumulated near the fence 6 and near a feeding port 5 (a front side of the fence 6) and the opposite side of the fence (a rear side of the fence 6) may realize a state in which the ignited materials are scarcely present. Accordingly, even if a state of making 'inner lid' for closing air blown from a lower side occurs at the front side of the fence 6, flame is not diminished at the rear side of the fence 6. With such an arrangement, even if a large amount of ignited materials is fed into the incinerator, no filling of non-ignited gas caused by air shielding may occur and so it is possible to avoid combustion accompanied by explosion.

Title: Decoding method using trace canceling method for viterbi algorithm and device therefor
Inventor: SAI KEISHIN
IPC: H03M13/23
Filed: 1996-10-30
Abstract: PROBLEM TO BE SOLVED: To prevent the deterioration of performance, owing to blocking by canceling a branch path coming into a state uncombined with the next state. SOLUTION: A number-of-path memory part 34 finds out the state at an nth time point which has not combined with the state at an n+1st time point by a surviving path, from number-of-path information, generates a path-canceling signal for deleting information showing a branch path in that state or from the state at an n-1st time point combined with the state, and deletes the information of the branch path from the path information supplied from a memory part 33. The number-of-path memory part 34 determines whether there is a branch path combined from the state to the other state at an nth time point, based on the number-of-path information corresponding to the state at the n-1st time point in which the information of the branch path is deleted.  If there is not, it generates a path-deleting signal to delete the information showing the branch path in the state at the n-1st time point or from the state at an n-2nd time point combined with that state, and deletes the information of the branch path from the path information.

Title: Malfunction preventing system for external bus input signal
Inventor: HANADA TADASHI
IPC: G06F11/00
Filed: 1987-11-16
Abstract: PURPOSE:To prevent the malfunction of a device caused by the error of a signal inputted from an external bus by providing a flag for showing a fact that an external bus input signal is received, on a processor for supporting various external bus input signals. CONSTITUTION:When a flip-flop (F1) 11 for showing the application of a power source becomes '1' again due to the malfunction of an input/output device side, a channel device 1 detects it. When a power source application receiving flag 12 is '1' already, it is regarded as the malfunction of an external bus input signal, and the F1 is canceled. As a matter of course, when the power source application receiving flag 12 is '0', when it is detected that the F1 for showing the application of the power source goes to '1', it is recognized as a normal power source application notice, the power source application receiving flag 12 is set to '1', and the F1 for showing the application of the power source is reset. In such a way, by providing the flag for showing a fact that an input signal is received, in addition to the F1 for inputting an external bus signal, the malfunction can be detected.

Filed: 1990-10-26
Abstract: PURPOSE:To shorten the holding time of an information channel by transferring a cell control signal through a control channel and then transferring the user information through the information channel after a communication channel is formed. CONSTITUTION:An ISDN network interface pert 102 transmits a control channel reception message 126 received from the control channel of an S/T point interface 124 to a maintenance date request detecting part 101 and a call detecting part 105 respectively. The part 101 detects a call setting message sent from a maintaining device out of the received massage 126 and then transmits a release end message 125 to the part 102 to show the rejection of the incoming calls. At the same time, a maintenance date request detecting signal 121 is produced at the part 101. Thus the holding time of an information channel is shortened.
